Food irradiation is one of a set of processing technologies that can be used to increase the microbiological safety and shelf life of a wide range of foods. Ionizing radiation is used to generate highly active chemical species within the food that react with DNA. Under normal usage conditions, the food receives a pasteurizing treatment that gives a valuable reduction in common food-spoilage org...

When food irradiation is carried out under Good Manufacturing Practice conditions, is commended as an effective, widely applicable food processing method judged to be safe on extensive available evidence, that can reduce the risk of food poisoning, control food spoilage and extend the shelf-life of foods without detriment to health and with minimal effect on nutritional or sensory quality. This...

Two types of radiations are used for preservation. They are ionizing radiations such as cathode and gamma rays and nonionizing radiation such as infrared and UV rays. The latter two have poor penetration and bactericidal properties. Ionizing radiations act by disrupting progeny cycles of pathogenic microorganisms by destroying DNA/RNA cycles. Thus, it enhances shelf-life of food and reduces mic...

by Paisan r^mong existing technologies for food preserLoaharanu vation, irradiation of food is recognized as a safe and effective method for a range of specific applications. Through its use, food losses and foodborne diseases can be reduced, and wider trade of many food items can be facilitated. A worldwide standard on food irradiation was adopted in 1983 by the Codex Alimentarius Commission o...
